108 Stab Wounds and No Jail Time: The Shocking Case of Cannabis-Induced Psychotic Disorder
A California woman stabbed her boyfriend over 100 times during a cannabis-induced psychotic episode—and received no jail time. This case challenges our understanding of intent, intoxication, and how mental health defenses are reshaping criminal accountability.

On May 27, 2018, a tragic and bewildering homicide unfolded in Thousand Oaks, California. Bryn Spejcher, a 27-year-old audiologist, fatally stabbed her boyfriend, Chad O’Melia, more than 100 times after smoking marijuana from a bong. The brutality of the attack left law enforcement, prosecutors, and the public in disbelief—not only because of the violence itself, but because Spejcher received no prison time.
Despite the overwhelming evidence of intentional violence, a team of medical experts testified that Spejcher was suffering from a Cannabis-Induced Psychotic Disorder (CIPD) at the time of the killing. Both the prosecution and defense experts agreed she experienced a severe psychotic break, rendering her “unconscious” of her actions. The court ultimately found her guilty of involuntary manslaughter, sentencing her to two years of probation and community service.
The Legal Framework
Under California Penal Code Section 187, murder requires proof of “malice aforethought,” meaning an intent to kill or a conscious disregard for life. However, medical testimony indicated Spejcher’s mental state did not meet that standard. The court instead applied Section 192(b)—involuntary manslaughter—arguing her voluntary decision to use cannabis led to the death, but without malice.
California law also recognizes “legal unconsciousness” as a complete defense when a person commits an act without conscious awareness. This rare legal concept, highlighted in People v. Newton (1970), became a key factor in Spejcher’s defense.
The Role of Cannabis-Induced Psychotic Disorder
Cannabis-Induced Psychotic Disorder is a recognized condition in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). It involves hallucinations, delusions, and a complete loss of touch with reality that can last days or weeks after cannabis exposure. Studies show that individuals with CIPD are at higher risk of developing chronic psychiatric conditions such as schizophrenia or bipolar disorder.
In Spejcher’s case, experts—including forensic psychologist Dr. Kris Mohandie—found her reaction to be genuine and severe. He concluded she was legally unconscious during portions of the attack, a finding that dramatically influenced the jury and sentencing outcome.
Why This Case Matters
For law enforcement officers, prosecutors, and legal educators, the Spejcher case raises serious questions:
When does voluntary intoxication end and involuntary mental illness begin?
How should courts weigh medical testimony against the brutality of the act?
Could the “unconsciousness defense” open doors to future challenges in criminal accountability?
While many see this verdict as a miscarriage of justice, others argue it reflects a growing recognition of the complex intersection between mental health and criminal law.
Final Thoughts
The case of Bryn Spejcher forces us to confront uncomfortable questions about responsibility, science, and fairness. It’s a reminder that the justice system is not only a legal framework—it’s a human one, constantly evolving with our understanding of the mind.
For officers and legal professionals, this case underscores the importance of recognizing signs of psychosis, understanding voluntary intoxication defenses, and staying informed on how mental health continues to shape modern criminal law.
